Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, specifically to a crushing silo for grain feed processing. Background Technology

[0002] In the field of grain feed processing, crushing silos are the core equipment for realizing the integrated operation of grain raw material storage, crushing and screening. They are widely used in large-scale breeding bases, feed processing plants and other scenarios. Their performance directly affects feed processing efficiency, product particle size accuracy and production continuity.

[0003] Currently, although existing grain feed processing crushing silos have achieved integrated functions of storage, crushing and screening, there are still many technical defects to be solved in actual application, making it difficult to meet the needs of efficient, precise and continuous processing.

[0004] First, the existing crushing silos have fixed roller spacing, which cannot flexibly adjust the particle size of the crushed material according to the feeding needs of different growth stages. The adaptability is poor, and multiple crushing equipment of different specifications are often required, which increases equipment investment and production costs. At the same time, it also occupies more production space, which is not conducive to large-scale production layout.

[0005] Secondly, during the screening process, large particles and impurities are easily trapped on the surface of the screen plate after crushing, which can easily cause screen blockage, reduce screening efficiency and discharge flow, and lead to the stagnation of subsequent processing. Traditional silos often use manual disassembly and cleaning to remove the trapped material on the screen, which is not only cumbersome and labor-intensive, but also seriously affects the continuity of production and significantly reduces the overall processing efficiency. If the screen plate is not cleaned for a long time, the material remaining on the screen plate is prone to bacteria and mold growth, which can contaminate the feed processed later, affect the hygiene and safety of the feed, and bring potential risks to livestock and poultry farming. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a grain feed processing crushing silo.

[0007] This utility model is achieved through the following technical solution:

[0008] A grain feed processing crushing silo includes a silo body. The interior of the silo body is connected from top to bottom and divided into an upper storage area, a middle crushing area, and a lower screening area. A pair of parallel crushing rollers are rotatably supported in the middle crushing area. The middle part of each crushing roller is coaxially fixedly connected to a rotating shaft. Both ends of the rotating shaft rotatably extend out of the shell of the middle crushing area. Both ends of the two rotating shafts are provided with adjustment components for adjusting the radial gap between the two crushing rollers, thereby controlling the particle size of the crushed material. Long strip-shaped slides that cooperate with the adjustment components are opened on both sides of the shell of the middle crushing area. A screen plate is fixedly installed in the lower screening area. A cleaning component for cleaning the material stuck on the screen surface is installed above the screen plate.

[0009] Further optionally, the adjustment assembly includes frame-shaped slide rails fixed on both sides of the housing of the intermediate crushing zone. The frame-shaped slide rails are aligned with the elongated slide rails. Two sliders are slidably connected in each frame-shaped slide rail. The sliders are used to rotate and support the end of the corresponding rotating shaft. A double-headed cylinder is provided between the two sliders in the same frame-shaped slide rail. The stroke of the double-headed cylinder is 0.5–3 mm. The cylinder body of the double-headed cylinder is fixedly connected to the housing of the intermediate crushing zone. The telescopic rods on both sides of the double-headed cylinder are fixedly connected to the sides of the two sliders in the same frame-shaped slide rail. A drive motor is fixedly connected to the two sliders on either side of the frame-shaped slide rail. The output shaft of the drive motor is synchronously connected to the end of the corresponding rotating shaft through a coupling.

[0010] Alternatively, the ends of the telescopic rods on both sides of the double-headed cylinder can be detachably and fixedly connected to the sides of the corresponding sliders by bolts.

[0011] Further optionally, the cleaning component includes lead screws that are rotatably supported on both sides inside the lower screening zone. One end of each lead screw extends to the outside of the lower screening zone housing and is synchronously driven and connected to the output end of the geared motor. A sliding nut is threaded and slidably connected to the lead screw. A suction pipe is fixed between the two sliding nuts. An air inlet is opened on the lower surface of the suction pipe. Chain-type air ducts are fixedly connected to both sides of the suction pipe. The other end of the chain-type air duct extends to the outside of the lower screening zone housing and is connected to the air inlet of the branch air duct. The air outlet of the branch air duct is connected to the air inlet of the main air duct. A bypass air supply duct is connected to the main air duct. The air supply duct inlet is connected to the air outlet of the fan.

[0012] Alternatively, the distance between the suction pipe and the sieve plate is 30mm-80mm, and the geared motor is connected and fixed to the outside of the lower screening zone housing via a bracket.

[0013] Alternatively, a material recovery bin is provided on the lower outer side of the silo body, and a chute inclined towards the center is provided inside the material recovery bin. A first discharge port is provided at the lower part of the material recovery bin, and a first control valve is installed on the first discharge port.

[0014] Alternatively, the main air duct outlet can be extended downwards and connected to the material recovery bin.

[0015] Alternatively, a feed inlet is provided at the top of the upper storage area, and a conical feed port is provided between the upper storage area and the intermediate crushing area, with a slide gate valve installed on the conical feed port.

[0016] Optionally, a second discharge port for discharging crushed material is provided at the bottom of the lower screening zone.

The interior of the silo body 1 is connected from top to bottom and divided into an upper storage area 2, a middle crushing area 3, and a lower screening area 4. A pair of parallel crushing rollers 5 are rotatably supported in the middle crushing area 3. The middle part of each crushing roller 5 is coaxially fixedly connected to a rotating shaft 6.

The ends of the two rotating shafts 6 are provided with adjustment components for adjusting the radial gap between the two crushing rollers 5, thereby controlling the particle size of the crushed material. Long strip-shaped slides 7 that cooperate with the adjustment components are opened on both sides of the shell of the middle crushing area 3. A screen plate 8 is fixedly installed in the lower screening area 4. A cleaning component for cleaning the material stuck on the screen surface is provided above the screen plate 8.

[0027] like Figure 1 , 2 As shown in Figures 3 and 5, the adjustment assembly includes frame-shaped slide rails 9 fixed on both sides of the housing of the intermediate crushing zone 3. The frame-shaped slide rails 9 are aligned with the elongated slide rails 7. Two sliders 10 are slidably connected in each frame-shaped slide rail 9. The sliders 10 are used to rotate and support the end of the corresponding rotating shaft 6. A double-headed cylinder 11 is provided between the two sliders 10 in the same frame-shaped slide rail 9. The stroke of the double-headed cylinder 11 is 0.5–3 mm. The cylinder body of the double-headed cylinder 11 is fixedly connected to the housing of the intermediate crushing zone 3. The telescopic rods on both sides of the double-headed cylinder 11 are fixedly connected to the sides of the two sliders 10 in the same frame-shaped slide rail 9. A drive motor 12 is fixedly connected to the two sliders 10 on either side of the frame-shaped slide rail 9. The output shaft of the drive motor 12 is synchronously connected to the end of the corresponding rotating shaft 6 through a coupling.

[0028] like Figure 1 , 2 As shown in Figures 3 and 5, the ends of the telescopic rods on both sides of the double-headed cylinder 11 are detachably and fixedly connected to the sides of the corresponding slider 10 by bolts.

[0029] like Figure 1 , 3As shown in Figures 4 and 5, the cleaning assembly includes lead screws 13 that are rotatably supported on both sides inside the lower screening zone 4. One end of each lead screw 13 extends to the outside of the housing of the lower screening zone 4, and its end is synchronously driven and connected to the output end of the reduction motor 14. A sliding nut 15 is threaded and slidably connected to each lead screw 13. A suction pipe 16 is fixedly connected between the two sliding nuts 15. An air intake 17 is provided on the lower surface of the suction pipe 16. Chain-type air ducts 18 are fixedly connected to both sides of the suction pipe 16, and the other end of the chain-type air duct 18 extends to the lower screening zone. The outer side of the shell of Zone 4 is connected to the air inlet of the branch duct 19. The air outlet of the branch duct 19 is connected to the air inlet of the main duct 20. The main duct 20 is connected to the bypass air supply duct 21. The air inlet of the air supply duct 21 is connected to the air outlet of the fan 22. The chain-type air duct 18 can move synchronously with the suction pipe 16, without pipe pulling or bending problems, ensuring smooth airflow throughout the process. It can be adapted to the reciprocating movement of the suction pipe 16. At the same time, a support plate is set on the upper part of the chain-type air duct 18 to provide support. The support plate is connected and fixed to the inner side of the shell of the lower screening zone 4.

[0030] like Figure 1 , 3 As shown in Figure 4, the distance between the suction pipe 16 and the sieve plate 8 is 30mm-80mm, and the geared motor 14 is connected and fixed to the outside of the housing of the lower screening area 4 through the bracket.

[0031] like Figure 1 , 3 As shown in Figure 5, a material recovery bin 23 is provided on the lower outer side of the silo body 1. Inside the material recovery bin 23, a chute 24 inclined towards the center is provided. A first discharge port 25 is provided at the lower part of the material recovery bin 23. A first control valve 26 is installed on the first discharge port 25.

[0032] like Figure 1 , 3 As shown in Figure 5, the main air duct 20 extends downward from its outlet and connects to the material recovery bin 23.

[0033] like Figure 2 The upper storage area 2 shown is provided with a feed inlet, and a conical feed port 27 is provided between the upper storage area 2 and the middle crushing area 3. A slide gate valve is installed on the conical feed port 27.

[0034] like Figure 1 , 3 As shown in Figures 5 and 6, a second discharge port 28 for discharging crushed materials is provided at the lower part of the lower screening zone 4.

[0035] like Figure 1 As shown, transparent observation windows 29 are respectively provided on the side walls of the intermediate crushing zone 3 and the lower screening zone 4.

[0036] The implementation principle of a grain feed processing crushing silo in this application embodiment is as follows:

[0037] When in use, the grain raw material to be processed is first fed into the upper storage area 2 of the silo body 1 through the feed inlet for temporary storage. The opening of the slide valve is adjusted according to the processing and production needs to control the grain raw material to enter the intermediate crushing area 3 at a uniform speed through the conical feed inlet 27, so as to avoid uneven feeding and cause load fluctuation of the crushing roller 5, and ensure the stability of the crushing operation.

[0038] Simultaneously, the drive motor 12 is started. The drive motor 12 drives the rotating shaft 6 and the coaxially fixed crushing roller 5 to rotate synchronously through the coupling. The grain raw materials entering the medium crushing zone 3 will be crushed by the crushing roller 5. When it is necessary to adjust the feed crushing particle size to adapt to different feeding needs, the double-headed cylinders 11 on both sides of the housing of the medium crushing zone 3 are activated. The travel of the double-headed cylinders 11 drives the telescopic rods on both sides to extend and retract synchronously (the extension and retraction length is set according to the site conditions). This pushes the slider 10, which is fixedly connected to the telescopic rod, to move synchronously towards or away from each other along the frame slide rail 9 and simultaneously with the slide rail 7 on the housing. The distance between the two rotating shafts 6 is adjusted synchronously, so as to increase or decrease the radial gap between a pair of parallel crushing rollers 5. This allows for flexible control of the particle size of the crushed material, adapting to the feeding needs of different growth stages. Moreover, it can achieve the crushing and processing of multi-specification feeds without replacing the equipment, greatly reducing the equipment investment cost.

[0039] The crushed material falls into the lower screening zone 4 and is screened by the screen plate 8. The finished material that meets the particle size requirements passes through the screen plate 8 and is discharged and collected through the second discharge port 28 at the bottom of the lower screening zone 4. During the screening process, the observation window 29 can be used to check whether there are many large particles and impurities retained on the surface of the screen plate 8. When it is observed that there are many retained particles on the surface of the screen plate 8, it needs to be cleaned.

[0040] During the cleaning operation, close the slide gate valve and stop the drive motor 12 to prevent the material from falling further. Then start the reduction motor 14 to rotate clockwise. The reduction motor 14 will drive the lead screws 13 on both sides inside the lower screening zone 4 to rotate synchronously, thereby driving the sliding nut 15 threaded on the lead screw 13 to move at a constant speed along the axis of the lead screw 13. At the same time, it will drive the suction pipe 16 fixed between the two sliding nuts 15 to move synchronously along the surface of the screen plate 8. The suction pipe 16 and the screen plate 8 are kept at a distance of 30mm-80mm to ensure the suction effect while avoiding interference with the screen plate 8.

[0041] Simultaneously, the blower 22 is started. The negative pressure airflow generated by the blower 22 is sent into the main air duct 20 through the air supply duct 21. When the airflow passes through the connection between the air supply duct 21 and the main air duct 20, a siphon effect is generated at the upper part of the connection between the main air duct 20 and the air supply duct 21, which in turn generates suction. The suction will enter the chain-type air duct 18 through the branch air duct 19 and then be sent into the suction pipe 16. At this time, the suction will continuously adsorb and collect the material retained on the surface of the screen plate 8 through the air intake 17 opened on the lower surface of the suction pipe 16. The adsorbed material and impurities are finally sent into the material recovery bin 23 through the main air duct 20. The material entering the material recovery bin 23 will be collected to the bottom of the material recovery bin 23 through the chute 24 inclined towards the middle. At this time, the first control valve 26 on the first discharge port 25 can be opened to discharge and recover the material. This not only completely solves the problem of screen hole blockage and ensures screening efficiency and smooth discharge, but also realizes the recycling of materials and reduces material waste and workshop dust pollution.

[0042] After the geared motor 14 is started, the controller of the silo body 1 will start counting. When the set value is reached (the set value is set according to the site conditions), it is equivalent to the sliding nut 15 driving the suction pipe 16 to move to the other end of the screen plate 8. After moving to the other end, the geared motor 14 is started to rotate counterclockwise, which in turn drives the suction pipe 16 to move in the opposite direction to reset. After returning to the original position, the cleaning operation is completed. After reaching the original position, the geared motor 14 is stopped, the fan 22 is turned off, the slide valve is opened, and the drive motor 12 is started to continue the crushing operation.

[0043] Throughout the operation, the operator can observe the internal crushing and screening conditions in real time through the transparent observation windows 29 set on the side walls of the middle crushing zone 3 and the lower screening zone 4. When abnormal situations such as material jamming, blockage, or material accumulation occur, the machine can be stopped in time to avoid equipment damage and material loss, and ensure production safety.

[0044] The entire operation process, through an integrated storage, crushing, and screening structure, combined with an adjustable component for the gap of the crushing roller 5 and a screen cleaning component, solves the technical defects of poor particle size adaptability of existing crushing silos and cumbersome cleaning and maintenance of screen plates 8. It realizes efficient, precise, and continuous crushing and processing of grain feed, greatly improves feed processing efficiency and product hygiene quality, and perfectly meets the production needs of large-scale breeding and feed processing.
